New research, published in PLOS Computational Biology, offers insight into the neural underpinnings of musical timbre. Mounya Elhilali, of Johns Hopkins University and colleagues have used mathematical models based on experiments in both animals and humans to accurately predict sound source recognition and perceptual timbre judgments by human listeners. A major contributor to our ability to analyze music and recognize instruments is the concept known as 'timbre'. Timbre is a hard-to-quantify concept loosely defined as everything in music that isn't duration, loudness or pitch. For instance, timbre comes into play when we are able to instantly decide whether a sound is coming from a violin or a piano.
